Abstract: Long-term, often overtime, operation of port structures leads to a significant reduction in the initial mechanical properties of steels, primarily resistance to brittle fracture. Possibilities of using electrochemical approaches to assess the operational degradation of metal structures of port cranes are analyzed. As indicator sensitive to operational change in a condition of steels, polarization resistance is chosen. The specificity of practical application of the electrochemical method as a non-destructive method for predicting the current mechanical properties of steels are demonstrated.
